To all whom it may concern:

' Be it known that I, ADAM A. VEBELUNAS,

a citizen of the United States, residing at Munhall, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Structural Forms, of which the following is a specification.

My invention relates to structural metal shapes-such as beams, channels, angles, plates and other forms and more particularly to forming such metal with an integral conduit or pipe for various uses.

The object of my invention-is to provide a cheap, simple and efficient form of structural metal shape which eliminates use of To enable others skilled in the art to I which my invention appertains to construct and use my improved structural metal shapes I will describe the same more fully referring to the accompanying drawings, in.

which Figure 1 is a front elevation of the rolls employed for forming the metal shape preparatory to finishing the conduit or tube. Fi 2 tur ned to form one half of the conduit or tube but before the same is welded down; Fig. 3 is a like view showing the welding or securing of the flange end to the main part of the channel form there shown. Figs. 4, 5, and 6 are cross sectional views of a channel showing the process of forming the intermediate flange into the outer half of a conduit or tube. Fig. 7 is a side view of a channel shape showing the manner ofconnecting the different lengths together. Fig. 8 is a view of the channel shape showing how a connection can be made at any point of theshape with the conduit or tube. Fig. 9 is a cross sectional view of the same on the lines 99 of Fig. 8. Fig. 10 is a side view of a channel shape showing another method of connection with the conduit or tube at any desired point. tional view of the same on of Fig. 10. p

Like symbols of reference herein indicate the lines 1111 is a. like view showing the flange tire length of the same. and rib 8 are formed by the faces 9 and 10 Fig. 11 is a cross sec-- Patented July 111T, jwjhfl.

like parts in each of the figures of the drawings.

" My .improved structural metal form or shape-is intended to eliminate the use of separate" pipes and conduits and their necessary supporting members and can be embodied in any forms such as angles, beams, channels, plates, etc, and although I have shown a channelform embodying my invention I do not desire to limit myself to that or any other particular shape.

In the drawings (Figs. 1 to 3) I have only shown the rolling from the time the metal has been formed into channel shape up tothe point of my invention as T have deemed it unnecessary to show the ordinarv breaking down from billet formj' finished channel shape as this is well. in this art. Therefore, Fig. 1 is intend illustrate the firstpass through thefr after the metal has been rolled to finished shape in cases where a regular channel is being formed.

As illustrated in the drawings 1 represents the lower rolls and 1 represents the upper roll of the first pass. In the first pass shown the channel shape 2 having the.

end flanges 3 is being provided with a semicircular groove or depression 4: and a flange 5, one side of which coincides 'with one side 7 or 1nner edge ofthe said groove or depres sionf. The groove 4: is formed by means of the portion 4 of the upper roll 1 while the flange 5 is formed by means of the slot 6 in said roll. The shape? is also provided with a shoulder 7 having its one side or edge coinciding with that side of the groove 4 opposite the flange 5 while the outer half of said shoulder has a rib 8 extending the en- This shoulder 7 1 said shape at the point where the groove 4 is placed. When the shape has been thus formed as described above it is ready for the next pass where the lower roll 1 is identical with-the lower roll of the preceding pass while the upper roll 13 is provided with a concave portion 14 for folding the flange 5 onto the shoulder 7 where rests on the upper face of the rib ;8 andsuch roll is also provided with the flat face for flattening 5 is thus turned over onto the shoulder 7 the conduit 17 will be formed the entire length of the shape 2 and the finishing.

thereof depends upon. the last pass or passes of rolls and whether or not it is necessary ,to put the metal through more than one pass .will depend entirely upon experiments which will be performed to determine this particular. In the last pass the roll 1 employed is identical with the lower roll used in the two described passes but the upper roll v18 is provided with a flange 19 which presses the metal of the flange 5 onto the 'inner half of the shoulder 7 and thus completely welds the same thereto.v This welding operation may require two passes through the rolls and may require being reheated before the parts are securely welded together but experiments will determine both of these essentials.

In Fig. 7 I have shown amethod of connecting the conduits 17 of several sections together or of connecting a separate conduit to the end of the conduit 17 as desired,'it being only necessary to tap threads '29 in the end of said conduit and either insert a pipe or inner coupling 21.

In Figs. 8 and 9 I have illustrated a method of drilling and tapping into the conduit 17 at any point desired and inserting a coupling 21 to which any desired connection can be made.

In Figs. 10 and 11 I have shown another point desired by merel removing a portion of the base of the s ape 2 to form the opening 22. The open ends of the conduit said couplings.

thereof and far enough therein to permit a T joint 23 to be inserted and connected with This would require sufficient threading in the conduit to screw at least one of the couplings 21 almost entirely into the conduit, in order to insert the T whereupon the coupling would again have to be screwed outward to unite with the T.

It will readily be seen that with the use of my improved structural .metal' form a great amount of pipe fitting will be saved and connections can readily be. madeat any place required.

A preferred use of my improved structural metal shapes is .for the bottom of railroad cars and such metal may be formed into any shape and the conduit used for carrying the compressed air for braking the speed of the car thereby eliminating the use of separate pipes and their necessary connections. My invention may, also' be used in building construction and the conduit 17 used to contain wires, etc., or the conduit may be used for carrying water, steamor other fluids.

' Various modifications and changes in the design, construction and application of my improved structural metal shapes Within the scope of the appended claims may be resorted to without departing from the spirit of the invention or sacrificing-any of its advantages.

- What I claim as m invention and desire to secure by Letters atent is:

1. A structural shape having a groove rolled ,therein, and an integral bendable flange adapted to cover said groove.

2. A structural shape having a groove rolled therein, and an integral bendable flange adapted to cover said groove, the

outer edge of said .bent flange being riveted to said structural shape.

In testimony whereof, I have hereunto set my hand. method of connecting the conduit 17 at any ADAM A. VEBELUNAS.
